不允许输入标点符号

Question

我想知道是否可以创建一个允许数字，字母和空格但没有标点符号的正则表达式。

发生了什么是我有一个在线贷款申请和街道地址字段中的一些用户在他们的输入中添加逗号（，）。在将应用程序导出为CSV时，由于地址字段中包含逗号，因此CSV文件在错误的地方包含逗号。

我一直在玩一个正则表达式几个小时，现在很好，但它不能完美。我偶尔会得到一个无法验证的地址，但它没有标点符号。否则它会是一个可接受的输入，但是正则表达式不允许它被验证。

所以不是我想什么规定是允许（数字，空格，字母），我不能只是规定了什么是不允许（标点符号）？后者比前者更有意义。

为了提供信息，我已经包含了用于测试我的正则表达式的地址列表。我还包括我一直在努力的正则表达式。任何指导或协助将不胜感激

注：我已添加注释，其中输入无效。在无效输入下面，我放置了一个现在有效的输入的编辑副本。

正则表达式：

/^(\w*)(\d+)(\w)?\s(\w+(\s?\w+?))+$/ 

Answer 1

为什么你需要为这个正则表达式？你可以这样简单的东西：

var address = "My address, with commas not allowed"; 
var newAddress = address.replace(",",""); 

正如我在评论说，用这种方法，你允许你的用户写的地址，因为他们想要的，但不破坏您的CSV分隔符。您将能够写一个地址，这样

街无处Nº10 - 2（12000）

而且它不会破坏你的CSV。正则表达式，该地址将是这样的：

街无处N 10 2 12000

这是较少的可读性。

Answer 2

更好的解决方案是用逗号逃离现场。见https://stackoverflow.com/a/769675/227299。您还需要转义任何双引号。

如果您在JavaScript这样做，你可以这样做：

function escapeCsvValue(val) { 
 
    if (val.indexOf(',') > -1 || val.indexOf('"') > -1) { 
 
     return '"' + val.replace(/"/g, '""') + '"'; 
 
    } 
 
    return val; 
 
} 
 
var csv = [ 
 
    ['Name, CommaForFun', 'Address'], 
 
    ['Jack','Calle Ocidental, 2'], 
 
    ['Jill O"quote"','125, The "cool" place'], 
 
    ['John','123 Main st'], 
 
]; 
 
    
 
var escapedCsv = csv.map(function(row){ 
 
    return row.map(escapeCsvValue).join(','); 
 
}); 
 

 
var csvString = escapedCsv.join('\n'); 
 
console.log(csvString); 
 
/* 
 
"Name, CommaForFun",Address 
 
Jack,"Calle Ocidental, 2" 
 
"Jill O""quote""","125, The ""cool"" place" 
 
John,123 Main st
